I think the project looks great, but didn't they go overboard and send unsolicited PMs to a lot of Yii forum members?
It's a pity.
I actually reported the project on Kickstarter, because there is no excuse for being spammy - no matter how cool the project is.

Hi everyone, Aaron here. First, apologies for the spamming. I had hired someone to help market the app to blogs where users would be interested, and clearly he went overboard instead emailing everyone.

We've made nice progress on our bug software and want to release a beta soon. I realized that as we are open source, I really should try to involve other users that are interested in helping so its not just me and my developers. If anyone would like to help build extensions or core functionality for the app, please send me a PM or write here. I would be happy to compensate for your time with free hosted BugKick accounts for life and some money from the funds we raised. Ideally we are looking for help spreading its usefulness, for example, mobile apps, plugins, extensions etc.
